A New Convenient Synthesis of Phosphoro(-no)Chloridothionates
摘要:
A general procedure for synthesis of phosphoro(-no)chlorides, particularly unsymmetrical ones, has been developed. The method involves the dealkylation of OTO-dialkyl phosphoro(-no)thionates 1 with dimethylamine and the chlorination of O-alkyl ammonium phosphoro(-no)thioates 2 using phosphorus oxychloride as a chlorinating agent.

A series of title compounds 2 were efficiently synthesized via the condensation of 1-phenyl-2-(1H-1,2,4-triazol-1-yl)ethanone oxime with various asymmetric thiophosphoryl chlorides in sodium hydroxide powder and acetonitrile system. The structures of title compounds 2 were confirmed by IR, (1)H NMR, (31)P NMR, EI-MS, and elemental analysis. The results of preliminary bioassays indicated that the title compounds 2 possessed good to moderate insecticidal activity against aphides at the dosage of 250 mg/L, and some of them exhibited moderate fungicidal activities at the concentration of 100 mg/L.
